You forgot the bit where “MU” told you your proposal was mostly
redundant, too limited and ad-hoc and would have security implications

I can't find a single thing about this in the ffmpeg documentation.
How is this called, where can I read more about it and - most importantly -
does it work out of the box?
No, it does not.
This was a suggestion that sounds like a better option than a custom

The result should be no need to provide "crypto://". The ffmpeg file format
detection should detect that ".crypto" should be handled by the crypto
plugin.
Instead of a custom descriptor file format that is only used for this

Hi,
The ffmpeg crypto protocol handler [1] allows one to play encrypted media.
The great thing here is that it allows playback of any media format that
ffmpeg supports!
Have a container format like mkv as an encrypted blob, no problem for the
